SLK squeak from engine pulleys

[nigxls]

Does anyone know if the likes of Gates do an idler pulley / tensioner kit for the 2.3 supercharged engine? I changed both belts as they were looking pretty cracked but I still have the squeaking noise, sounds bearing related to me.

Depending on the engine fitted (111.973 or 111.983) there is a tensioner, idler pulley or a kit for your car.
Its either this one

MERCEDES SLK230

Or more likely this one.

Thanks for that, I just need the idlers and tensioners probably as the belts have just been done. Mine is the 973 by the looks of it.
